PROBLEM TO BE SOLVED: To simply support a steel form at a low cost for pouring concrete which is arranged by surrounding the vicinity excluding the upper portion of a beam member arranged by coupling between both the steel columns. SOLUTION: At the bottom plate portion of a channel-shaped steel form 30 comprising a pair of parallel plate portions 31 which are parallel and facing each other and a bottom plate portion 32 connecting both of them at a right angle at one end of the plate portions, plural sets of insertion holes are provided at each pair of two places in the width direction at plural places in the longitudinal direction. By using a suspension member 35 made of a metal rod comprising a pair of leg portions 36 facing and parallel each other and a coupling portion 37 connecting both of them at a right angle at one end of a pair of leg portions, their coupling portion is placed at the upper side of steel and the leg portion is suspended, the lower end side of the leg portion is inserted to a pair of insertion holes of the steel form, a fixed member is attached to a projected end portion from the insertion hole, and the bottom end side of the leg portion is inserted to a pair of insertion holes of the steel form, a fixed member is attached to the projected end portion from insertion hole and the steel form is suspended by the suspension member for supporting purpose.
